MICROPHONE INSTALLATION (Figure 2)

The microphone is most stable when the gooseneck is bent

into a "lazy S" shape as shown in Figure 2. Use the supplied

hanging clip and heavy thread or monofilament fishing line to

suspend the microphone at a specific location.

INSTALLING THE FOAM WINDSCREEN (Figure 3)

1. Press the foam windscreen onto the microphone until it

snaps into the groove located behind the cartridge.

2. To remove the windscreen, spread the gap in its mount-

ing ring with a screwdriver or thumbnail and pull the

windscreen off.

PREAMPLIFIER INSTALLATION

Plate-Mount Preamplifier Input Connections

1. Detach the preamplifier housing by removing the two

Phillips head screws from the back of the housing.

2. Remove the material from the hole in the center of the

cover plate or the center of the preamplifier housing.

3. Cut the cable to the desired hanging length, allowing for

a 76 mm to 101 mm (3 to 4 in.) service loop.

4. Clamp the strain relief around the cable and insert the

strain relief into the hole.

5. Connect the cable leads to the terminal block (B = Black,

R = Red, S = Shield).

Plate–Mount Preamplifier Output Cable Connections

1. Using professional-quality, two-conductor, shielded micro-

phone cable, thread the output cable from the outside of

the preamplifier through the hole with the black bushing.

2. Connect cable to pins as follows: Pin 2 = +, Pin 3 = –,

Shield = S.

3. Reattach the preamplifier housing.

Installing the In-Line Preamplifier (Figure 4)

Use the two supplied mounting clamps to hold the pream-

plifier in place on a wall or ceiling. Set the length of the cable

by cutting it appropriately and using the screw terminal con-

nections inside the preamplifier. The terminals are marked

B (black), R (red), and S (shield).

Adjusting Preamp Gain (Figure 5)

This MX microphone includes an adjustable gain preamplifi-

er, allowing the user to specify a 12 dB or 0 dB gain setting. The

preamp ships at the 12dB setting. Gain may be decreased by

12dB by moving the preamp jumpers to the 0dB setting.
